Answer:
P = (10 + 2√13) ft ≈ 17.21 ftStep-by-step explanation:
A = 12 ft² - area of triangle
a = 4 ft, b - legs of right triangle
c - hypotenuse (third side of triangle)
A = ¹/₂ ab
12 = ¹/₂•4•b
12 = 2b
b = 6 ft
from Pythagorean theorem:
a² + b² = c²
4² + 6² = c²
c² = 16 + 36
c = √52 = 2√13 ft
The perimeter: P = a + b + c
P = 4 + 6 + 2√13 = (10 + 2√13) ft ≈ 10 + 7.21 = 17.21 ft

Megan wanted 50 beads that were originally $9.95. She had a coupon for 25% off and paid a sales tax of 6%. What was the total she paid for the beads?
9.95(0.75)(1.06)=7.91
The .75 is the coupon and 1.06 is the sales tax.
If the sales tax is 6%, add the decimal version of 6% to 9.95.
6% ⇒ 0.06
9.95 + 0.06 = 10.01
Since Megan has a 25% off coupon, find 25% of the full price by multiplying 0.25 by 10.01.
25% ⇒ 0.25
10.01 × 0.25 = 2.50
Now subtract 2.50 from 10.01.
10.01 - 2.50 = 7.51
Answer:The total price of the beads is $7.51.

which expression can be used to find the surface area of the following square pyramid
Answer:
a. 36+15+15+15+15
Step-by-step explanation:
The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.
The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.
Hope this helps :)
